All specifications on this page were taken directly from Bad Boy, the manufacturer. Figures from Bad Boy Rebel SD specs, checked November 2, 2026: Bad Boy Rebel SD specs. "Width (deck out)" is the OEM "Width (Chute Up / Chute Down)" figure given both ways.

One engine, two decks

The Rebel SD keeps the choice simple. Both the 54 and the 61 run the Rehlko Confidant ZT740, a 747 cc engine rated at 25 hp. Power goes through a Hydro-Gear 4400 16cc integrated transaxle, with a top speed of 12 mph. The tank holds 13 gallons, so a long day doesn't mean a lot of stops. Since the engine's the same on both sizes, the only real decision is the deck.

The deck's 1/4-inch, or 3-gauge, solid steel with reinforced 3/8-inch sides. It cuts from 1 to 5 inches. The 54 weighs 1,257 lb and the 61 weighs 1,382 lb. Rear tires are 24x12-12 Reapers, and the fronts are 13x6.5-6 smooth.

Who picks the SD

It's a heavy-deck zero-turn for someone who'd rather not sort through a list of engines. Maybe you keep a big place cut yourself, or you mow a few properties on the side. The comfort seat comes with adjustable handles and pedals, so you can set it to fit you.

Width matters with a deck this size. With the chute up, the 54 is 56.5 inches wide and the 61 is 63.5. Chute down, they're 68.5 and 75.5. Measure your gate and your trailer before you choose. Want more horsepower or a bigger deck? Look at the Rebel.

Mowing your own few acres plus a neighbor's? The 61 covers more on each pass. The 54 is the one to pick if your gate or your trailer is tight. The 1-inch low setting gives you a tight cut on a lawn you keep short.
